T2DM was linked to a mild reduction in bilirubin and γ‐tocopherol levels (OR = 0.988, 95% CI = 0.978–0.998 and OR = 0.982, 95% CI = 0.966–0.998, respectively, Figure 8), while slightly increased levels of HO‐1, albumin, and urate (OR = 1.139, 95% CI = 1.014–1.281, OR = 1.044, 95% CI = 1.031–1.057, and OR = 1.059, 95% CI = 1.034–1.084, respectively, Figure 8). This evidence concerns the gene ALB and type 2 diabetes mellitus.
